_j 1.2
Each persona's IPS profile below is a real _j 1.2 JSON payload, identical in shape to what the JemmaPass app reads from a QR scan. The profiles are clinically realistic and used verbatim in the demo video.
Background. 58 years old, retired civil servant from Brussels, walking the Shikoku 88-temple pilgrimage for spiritual reasons. He speaks French natively, conversational English, and no Japanese. He carries an EpiPen because of his severe penicillin allergy, with a documented history of anaphylaxis.
Why he matters in the demo. Kurodo is the patient who triggers the killer moment. His IPS profile, embedded in a 500-byte QR worn around his neck, contains a SNOMED-coded penicillin allergy that JemmaPass walks the ATC hierarchy on to flag Augmentin as contraindicated — preventing a fatal anaphylactic reaction during the earthquake aftermath.

}91936005 for penicillin allergy. When Kamekichi scans Augmentin (ATC J01CR02), JemmaPass walks the ATC hierarchy up to J01C* (penicillins), matches it against Kurodo's allergy, and triggers the red alert. The patient summary itself is the safety check.
Background. 80 years old, lives alone in rural Aomori. Mild congestive heart failure, seasonal allergies (treated with Allegra FX), occasional bronchitis (treated with Medicon Pro dextromethorphan). She speaks only Japanese, has no smartphone proficiency. Her grandson encoded her IPS profile and printed it as a Pocket Pass she keeps in her wallet.
Why she matters in the demo. Haru represents the "paper IPS" use case — for people who can't or won't use smartphones. Her printed badge is scanned by Kamekichi's app and by an iPhone using the native Camera app, proving JemmaPass interoperates with non-JemmaPass devices via its multilingual text channel.

}Background. Kamekichi (亀吉, "lucky turtle") is the brand mascot AND the rescuer protagonist of the demo scenario. A disaster relief volunteer in Shikoku, he's not a doctor — just a regular citizen with the JemmaPass app installed. The turtle motif comes from the Silicon Shell metaphor: the back shell holds the AI brain (Gemma 4), the front plastron displays the patient's QR.
Why he matters in the demo. Kamekichi demonstrates the Rescuer Mode — the most critical use case. He scans Haru's printed badge, receives Kurodo's SOS over Nearby (no internet), and uses the @Tool drug-allergy cross-check to detect the Augmentin × penicillin contraindication. He proves JemmaPass democratizes clinical safety for non-medical first responders.

On the day of the M 7.6 Shikoku earthquake, all three personas connect within 20 minutes — without any internet, cell tower, or cloud server.
Cell towers collapse. Kurodo is injured. He activates SOS Mode on his Pixel 9 (a double-tap on the lock-screen widget — no unlock, no app launch). His JemmaPass begins broadcasting his pruned IPS via Nearby Connections.
Kamekichi, 800 m away, sees Kurodo's SOS appear on his radar UI. The full IPS profile arrives via 5 BLE chunk reassemblies. Profile auto-renders in Japanese.
On the way, Kamekichi encounters Haru. He scans her printed Pocket Pass with ML Kit. Her IPS appears instantly. He scans her medication box → green check.
Kamekichi reaches Kurodo. He's about to give him Augmentin from his vest. He scans it first → red alert: beta-lactam cross-reactivity with penicillin allergy. Anaphylaxis averted.
Zero internet packets exchanged. Zero cloud server contacted. Zero medical training required of Kamekichi. One life saved — by 200 ms of on-device clinical reasoning.
The personas you just inspected appear verbatim in the 3-minute demo video. Watch them come alive.
